Abstract  Abstract

The invention claims systems and methods that facilitate utilizing power control preambles with closed loop power control techniques in a wireless communication environment. can be on the downlink transmitting uplink grant (e.g. the uplink active state after the first uplink grant) and as a response to the uplink grant can send power control preamble on an uplink. According to an example transmission of the power control preamble can be for explicit scheduling and/or scheduling of implicit. can be on the power level determined by an access terminal utilizing an open loop power control mechanism of sending the power control preamble. the base station can analyze the power control preamble and generate a power control command based on the analysis so that the power level used by the access terminal for performing correction. Then the access terminal can utilize the power control command to adjust the power level for uplink data transmission.
